Chess Puzzle of the Week (410)

Bob and Carol were back at Cambridge Park Bowls Club after the summer holidays, and surprised by what they saw.

“What a lot of new members here! It will be great to get to know them all, wouldn’t it, Carol?”

“A lot of them are women as well. And they’ve just started a new junior group. We’ll have to bring our kids along next week. I’m sure their friends would love it too.”

They soon settled down to play and had reached this position when Ted and Alice arrived. Carol, playing Black, was just about to play her seventh move.

“Interesting position”, exclaimed Ted. “Are you trying out a new opening?”

“Wait a minute!”, added Alice. “I think I’ve worked out what the first moves were.”

Can you do as well as Alice? How did Bob and Carol reach this position after White’s seventh move?

Chess Puzzle of the Week (409): Solution

I left you with this simple pawn ending with White to play on Monday.

It looks obvious for White to continue with b4, a4 and b5 here, but, as White discovered in the game, it’s only a draw. You’ll queen your h-pawn first, but the resulting QvP ending will be drawn.

Paradoxically, the only winning move here is a3, which superficially appears to be a move slower, but reaches a winning QvP ending because you promote on h8 when the black king is on b3 rather than b2.

Would you have found this playing on increments?

Chess Puzzle of the Week (408): Solution

This is Philidor – Wilson (London 1789). Black has just mistakenly moved his rook to e8 (d8 would have been better). I’m sure you can do better than Philidor and find the best continuation here.

I suggested on Monday that, judging from games like this, Philidor might have struggled to make our C team.

Perhaps I was right: first with the correct answer was C/D team star (and one of the team behind our successful new junior group) David.

White should have continued 29. Re1!, continuing, for example, 29… Qf7 30. Rxe8+ Qxe8 31. Qe5 and White is winning the ending.

Instead he played the imaginative but sub-optimal 29. Qe5!?. Black lost the ending quickly after Qxe5, but 29… Qd8! holds after, for example, 30. Qxe8!? Qxe8 31. Rc8 Qxc8 32. Ne7+ Kf7 33. Nxc8.

The game was played at unusual odds: Philidor played without his queen’s knight and his opponent without his f-pawn.

Thanks to Roger Scowen for informing me that today marks the 300th anniversary of the birth of the great François-André Danican Philidor, a renowned composer of operas, instrumental and sacred music, but also the leading chess player of the 18th century. He was the first player who had a genuine understanding of many positional concepts.

Of course chess has moved on a lot since then: looking at his games I think he’d struggle to find a place in our C team.

This is Philidor – Wilson (London 1789). Black has just mistakenly moved his rook to e8 (d8 would have been better). I’m sure you can do better than Philidor and find the best continuation here.

An Entertaining Game

Mike Healey has annotated his game from our London League match against Streatham last May.

If you’re familiar with Mike’s play you’ll know what to expect. As he says, an interesting and hard-fought game, with some interesting ideas and many wacky positions.

Chess Puzzle of the Week (406): Solution

On Monday I left you with this position from Adam A Taylor (2269) – Sanjit Kumar (2074) (Kingston 2026 Round 3) with white to play.

Black’s last move, 71… Rf1-h1, was a blunder. The four drawing moves were Ra1, Rb1, Rc1 (good to get as far away as possible from the white king to check horizontally) and Kh7.

Now White could have brought home the full point by playing for mate.

72. Kf6 Kh7 (72… Rxh4 73. Rg7 f3 74. g5+ Kh5 75. Kf5) 73. Kxf7 Rxh4 74. Rg7+ Kh6 (74… Kh8 75. g5 f3 76. Rg8+ Kh7 77. g6+ Kh6 78. Rh8+ Kg5 79. g7 f2 80. g8=Q+) 75. Rg6+ Kh7 76. g5 f3 77. Rf6 and wins.

Sadly for him, he missed his chance, playing 72. Rh5+ instead, and the game was drawn on move 85.

Not so easy, of course, at the end of a long and tiring game with little time left on the clock. Which is why you need to practise endings if you want to improve.
